VEHICLE SANDING DEVICE Application filed DecemberLZG, 192?. Serial No. 416,625.

Elly invention relates to improvements in sanding' d'evices to prevent the skidding of automobiles and has for its primary object to provide a novel and improved device of this'character which is very simple in construction, convenient to ihstalland highly efficient in practical use.

T he invention also contemplates a device of this character incorporating means for seeping the sand supply in a heated usable condition.

Another object of the invention resides in the provision of novel valve control means for regulating the sand supply, which means will be always accessible and which will be prevented from freezing and-sticking.

'Another object of the invention is to provide seoarate supply means for positively directing same to individual wheel paths. I

The invention also resides in certain novel features of construction, combination and arrangement of parts, all of which will be readily understood and appreciated by those skilled in the art upon reference to the accompanying drawing forming a part of this specification.

While the drawing illustrates what is now regarded as a preferred mechanical expression of the invention the same is susceptible 3 of various 'changes and modifications within the spirit and scope of the subject matter claimed hereinafter.

In the drawing, Figure 1 is an clevational view partly broken and partly in section illustrating the application of my invention to an automobile; Figure 2 isa frontelevational view partly broken and partly in section and showing my invention; a

Figure 3 is a horizontal sectional view taken on the line 3-3 of Figure 2:

Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 2; and

Figure 5 is a sectional view taken on the line o-f of Figure 2. l

. Referring specifically to the drawing numeral 8 designates the cowl partition of the vehicle having the dash board 5 and whose frontseat provides a chamber 7 therebeneath,-which may have bracketed therein the sand box 8 having the hopper-like bottom 8 and the top closure 8*.

i The bottom of the sand box 8 has two outlet holes 9 communicating with nipples 9", there being provided bet-ween the nipples 9 the bearing 10 for the valve control stem 11 having the valve 12 resting upon the bottom of the box. One branch of'the valve is adapted to seal one of the holes 9 while the other branch seals the other hole 9. Stops 12 are arranged upon the bottom of the box 8 to limit rotation of the valve 12, one or the stops 12 being disposed as in Figure 3 to limit movement of the valve in the direction of the arrow in Figure 3. l'he valve is normally urged in the direction of the arrow (Figure 5) by the spring 14 which is secured to one end of the cross member 15 rigidly mounted upon the lower end of the valve stem 11 as indicated at 16 in Figure 2. The actuating wire 17 is attached to the other arm ofthe cross member 15 and leads up through the guide tube 18 which is carried by the cowl partition as indicated at Figure 1,-the end of the wire being connectcd to the pull connection 19 suitably socketed in a guide keeper of the dash 5.

Fi'rure 2 illustrates that the valve stem carries the cap 12 which is clamped against the head of the valve hub by means of the screw 13 entering the end of the valve stem 11.

The outlet nipples 9 are connected to the respective sup ly branches 24) having the con stricted elongated outlets 20 immediately in front of the rear traction wheels 22. Suitable brackets 23 are provided for supporting the p pes 20 adjacent their discharge ends,-the-.e brackets being suitably secured to the. frame or body of the vehicle.

Figures 1 and 2 illustrate that the exhaust pipe 24 is provided with branches 25 leading laterally therefrom and connected each to one of the sand supply pipes 20 whereby to keep same heated, to the end that the sand in the box 8 will be maintained in a dry and usable condition and kept from freezing.

It is furthermore emphasized at this point that the exhaust pipe is arranged below the valve stem and bearing 11, 10 so that same will be kept against sticking or freezing. Figure 1 illustrates that the spring 14 is secured to the body at its remote end as indicated at 14.

The valve 12 will be maintained in close contact with the bottom of the box 8 by the action of the cap 12 and screw 13 which draws the lower shoulder 11 of the valve tightly against the lower end of the bearing 10 as indicated in Figure 4.

The provision of separate supply conduits 20 assures an equal distribution of sand to the area in front of each rear wheel 22.

It is believed to be obvious that a simple pull upon the member 19 (Figure 1) will effect actuation of the valve 12 to uncover the openings 9 permitting the sand to flow down the tubes 20 in an obvious manner.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is;

1. A sanding device for automobiles comprising a sand supply container having spaced outlets in its bottom, a valve stem bearing extending from said container bottom at a point between said outlets, a rotatable valve adapted in one position to simuL taneously close said outlets, spring means normally tending to urge said valve in a direction to close said outlets, stop means adapted to engage said valve to limit movement thereof under the influence of said spring, a cross-head rigidly secured to said spring, said valve having a stem extending through said bearing and carrying said crosshead beneath said container, the spring being connected to one end of said cross-head, means operable from the drivers seat of the vehicle and connected to the other end of said cross head for actuating said valve against the tension of said spring, said cross-head being disposed below said outlets. discharge connections communicating with said outlets and arranged at either side of said bearing and cross-head and converging toward one another in the direction of said container above said cross-head, the exhaust manifold of the automobile being arranged immediately below said cross-head and bearing and having connection branches communicating with said discharge connections whereby to communicate heat thereto tor transmittal to said container and bearing through said discharge connections. and means for maintaining said valve in contact with the bottom of said container and for holding said stem in assembly with said valve.

2. A sanding device for automobiles comprising a sand supply container having spaced outlets in its bottom, a valve stem hearing extending from said container bottom at a point between said outlets. a rotatable valve adapted in one position to simultaneously close said outlets, spring means normally tending to urge said valve in a direction to close said outlets, a cross-head rigidly secured to said spring, said valve having a stem extending through said bearin and carrying said cross-head beneath sai container, means operable from the drivers seat of the vehicle and connected to said cross head for actuating said valve, said crosshead being disposed below said outlets, discharge connections communicatin with said outlets and arranged at either side of said bearing and cross-head and converging toward one another in the direction of said container above said cross-head, and heat supply branches connected to said discharge connections whereby to communicate heat thereto for transmittal to said container and bearing through said'discharge connections.

3. A sanding device for automobiles comprising a sand supply container having spaced outlets in its bottom, a valve stem bearing extending from said container bottom at a point between said out-lets, a rotatable valve adapted in one position to simultaneously close said outlets, spring means normally tending to urge said valve in a direction to close said outlets, stop means adapted to engage said valve to limit movement thereof under the influence of said spring, a cross-head rigidly secured to said spring, said valve having a stem extending through said bearing and carrying said cross-head beneath said container, the spring being connected to one, end of said cross-head, means operable from the drivers seat of the vehicle and connected to the other end of said cross-head for actuating said valve against the tension of said spring, said cross-head being disposed below said outlets, discharge connections commnnicatin with said outlets and arranged at eit ier side of said bearing and cross-head and converging toward one another in the direction of said container above said cross-head.

4. In amotor vehicle having an exhaust pipe and sand box, the combination of separate diverging outlet means in said box, a single control valve for said outlets intermediate the same, and the exhaust pipe being between said outlet means and adjacent said valve for heating the valve and outlets.

In testimony whereof I attix my signature.
